La Morena Mariscos on Broadway in Chula Vista is a Latino-owned mariscos counter serving Baja-style seafood alongside birria and adobada tacos from a kitchen that also supplies a second location on Sweetwater Road in Spring Valley. The kitchen runs a raw-bar program through the same South Bay seafood network that supplies Santa Fe Meats Mercado, turning out ceviche mixto, aguachile tostadas, and aji tuna dressed with cucumber, avocado, and sesame seeds. Cooked plates expand the menu into a 7 Seas soup, marlin burritos, shrimp cocktails layered with pico de gallo, and a seafood tower built for group service. Catering-sized tray orders of tacos and mariscos platters position the restaurant as a South Bay event option, feeding the same Broadway corridor crowd that sources conchas and tres leches from La Concha Bakery for celebration spreads. The Tostada Especial layers octopus, cooked shrimp, pico de gallo, cucumber, and avocado onto a single crisp corn base — a multi-protein raw-bar assembly that anchors the house specialty menu.
